You can't say these triangles are similar by SSA because that is not a criterion for triangle similarity. However, because these are right triangles, you know that the third side of each triangle can be found with the Pythagorean Theorem. For the smaller triangle: 12 2 + x 2 = 15 2 → x = 9. For the larger triangle: 36 2 + x 2 = 45 2 → x = 27.The long leg is 5 3. So, the short leg is 5 in. Start with the missing angle measure. The sum of all the angles in a triangle is 180°, so the missing angle is 30°. This is a 30°–60°–90° triangle. SL = LL = 3. H =.

AboutTranscript. The sum of the interior angle measures of a triangle always adds up to 180°. We can draw a line parallel to the base of any triangle through its third vertex. Then we use transversals, vertical angles, and corresponding angles to rearrange those angle measures into a straight line, proving that they must add up to 180°.©Edgenuity Inc.

Firstly, if the triangles have 2+ matching corresponding angles, then it is similar. If it has side lengths that can be divided by a number, say X, and then match the side lengths of your other triangle, then it is similar. If it has 2 matching corresponding (see last sentence) sides, and the angle between these is the same, then it is similar. The long leg is 5 3. So, the short leg is 5 in.
